For Developers

Hi,
Iam new to Operwrt, i tried to pull Openwrt from git hub and tried compiling for Qualcomm 40xx controller, during the process i get error. I followed below steps

  1. git clone https://git.openwrt.org/openwrt/openwrt.git
  2. cd openwrt
  3. ./scripts/feeds update -a
  4. ./scripts/feeds install -a
  5. make menuconfig ( Selected Qualcom 40xx )
  6. make
    I get below error
-- Ccache version: 4.7.4
-- Ccache dev mode: OFF
CMake Error at cmake/StdFilesystem.cmake:22 (message):
  Toolchain doesn't support std::filesystem with nor without -lstdc++fs
Call Stack (most recent call first):
  cmake/StandardSettings.cmake:57 (include)
  CMakeLists.txt:70 (include)

And stops, tried to search menuconfig to disable stdc++fs , but no success.
Anyone could you please let me know how to go ahead. Thanks

First start again with make -j1 V=sc

It seems other toolchains have similar problems with ccache 4.7.x. So as a short time "fix", well bypass the problem, Unselect "use CCACHE" or try and downgrade ccache.

Thank you all for suggestions. Issue resolved.
I had enabled Build OpenWrt SDK option under make menuconfig.
After disabling the above option now its compiling.
Thanks for your time
